The SKM400GB12E4 is a high-voltage, high-current IGBT half-bridge module manufactured by Semikron. It features a maximum blocking voltage of 1.2kV, peak current of 400A, and peak forward surge current of 1.2kA. The module is equipped with a SEMITRANS3 current-driven table, which enables easy control of the gate current and turn-on/turn-off timing of the IGBTs. Additionally, the module has a temperature sensor, a temperature compensation circuit, a temperature alarm output, and a voltage alarm output. It is suitable for high-power motor and traction applications.
